Title: IPOD HIFI dock/speaker constant buzz. where to find schematic?
Post by: N4v4jo on February 29, 2024, 02:20:08 pm

Hi all

I have an old IPOD HIFI dock-speaker. When I connect an Ipod in the dock or any audio signal in the AUX port I get a constant buzz. I'm trying to repair but I need the schematic. I have been searching for a couple of weeks already but I haven't found anything. Does anybody know where I could find it?.

Thank you in advance.

Schematics for an Apple product? Good luck with that.
Ask Louis Rossmann about getting anything from Apple for repairs. https://www.youtube.com/watch?v=2jCtVDCiY_8 (https://www.youtube.com/watch?v=2jCtVDCiY_8)

With that being said I would check any coupling and decoupling caps. Specifically electrolytic capacitors concerning the power supply if the buzzing sound is at 120Hz. Check the dock connector for broken or deformed contacts.
